The business, Marty's Diesel Garage LLC, started as two friends, Clarence and myself Marty hanging out in my back yard garage after work, working on our own cars. We bought a Chevy truck from a friend at work that didn’t run, fixed it up, and sold it. We had fun doing it and started buying hand-picked vehicles through a local dealer. We would buy the best quality cars we could afford go over them front to back mechanically and sell them. As our hobby became more successful we decided to move to the next level and have our own used car dealership. Since it was our hobby we decided to call our new business Hobby Auto. We spent the next couple of years taking our vacation time off work to run to auctions to buy cars and spent our evenings repairing and selling them. Our motto in the car business that we lived by, was whether a customer was spending five hundred dollars or ten thousand dollars, that's what they could afford and they did not need unexpected repairs after they bought the vehicle. We worked hard at having our cars ready for trouble-free service after the sale. With all the hard work Clarence and I put into buying and selling cars there was very little financial reward to put in our pockets after all the bills were paid. Clarence moved on and I became a sole proprietor operating under the name of Hobby Auto Sales. I continued with the dealership but added a service department. With the help of another childhood friend, Mike, our service department grew rapidly.  Mike’s knowledge and technical experience on the automotive side combined with my knowledge and background in heavy truck and auto repair, and our willingness to work on anything at any time caught the eye of a local business owner, Silvio Corte. I credit a lot of our success to Silvio, he not only provided us with steady work and a platform to grow on, but also passed on lessons in customer service, persistence, and good honest handshake business practices that we use with all our customers small and large.

It’s far from a hobby today, we no longer sell cars, we changed the name to Marty’s Diesel Garage, LLC. I don’t work on cars and trucks as much as I like to. Mike is now our night shift supervisor. We have added several great employees along the way that continue to help us grow and provide better ever-changing customer services.  If you have auto or truck repairs in the Homer City - Indiana County PA area, we ask that you choose to use Marty's Diesel Garage, LLC.
